New Yorkers came in 2nd in a nationwide study tracking complaints filed to 311. In 2009, the city's 311 center "received 224 calls for each 100 residents, compared with 446 in San Francisco, 185 in Charlotte, N.C., 152 in Baltimore, 151 in Chicago, 110 in Miami and 101 in Houston." And here we thought SF was so mellow. So what are we complaining about? CityRoom says our top concerns were noise, alternate-side-of-the-street parking regulations, lack of heat or hot water, bus or subway service, and lost property in taxis. And over on the west coast, they're worrying about street cleaning, graffiti removal, public housing services, and abandoned vehicles. Hey Midtown, speak up a little more and maybe we can be #1 next year.
